It is believed that these tubercles simply reflect light and are not luminescent. These tubercles are commonly (and incorrectly) described as phosphorescent in spite of much scientific evidence to the contrary. There are several "prominent rounded tubercles" with an "opalescent lustre" at the back of the gape. Selective breeding has also developed mutations (blue, yellow and silver instead of a green back) in both body and breast colour. Formerly considered three different kinds of finches, it is now known that these are colour variants that exist in the wild. Gouldian finches' heads may be red, black, or yellow.
